TECHNICAL FIELD

Embodiments of the present invention relate to communications technologies, and in particular, to a remote electrical tilt unit, a base station, and a method for managing a remote electrical tilt antenna.

BACKGROUND

A remote electrical tilt unit is built in an antenna, and during installation, a mapping relationship between the antenna and the remote electrical tilt unit does not need to be recorded, which simplifies a configuration process of the antenna and a remote electrical tilt device, and makes the installation of the antenna and the remote electrical tilt device more convenient and efficient. If it is required to use multiple frequency bands to cover a same area, an operator commonly uses a multi-band antenna to replace a single-band antenna. The multi-band antenna has advantages such as avoiding multiple times of antenna installation and saving occupied space. Therefore, building a remote electrical tilt unit in a multi-band antenna becomes a development trend of an antenna. However, when multiple base stations share a multi-band remote electrical tilt antenna, abase station needs to support management of multiple multi-band remote electrical tilt antennas.

Generally, communication between abase station and an antenna is implemented based on the Antenna Interface Standards Group (AISG) standard. Multiple base stations are connected to different AISG ports of the antenna to perform configuration management on a remote electrical tilt antenna. A remote electrical tilt unit (RET) can be configured by only one base station corresponding to an AISG port. In the prior art, however, it is difficult to locate and troubleshoot a fault in a scenario of incorrect configuration of the RET.

To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following clearly describes the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

In a remote electrical tilt antenna provided by an embodiment of the present invention, a control unit is built in the antenna, at least two groups of AISG ports are provided externally to function as control ports of remote electrical tilt units, where each group of ports provides a same function. Multiple remote electrical tilt units are disposed inside the remote electrical tilt antenna, and the multiple remote electrical tilt units share one control unit. For example, the remote electrical tilt antenna device provided by the embodiment of the present invention may be a tri-band antenna with two AISG ports shown in FIG. 1, where the tri-band antenna with two AISG ports presents two AISG ports and three remote electrical tilt units externally; or the remote electrical tilt antenna device provided by the embodiment of the present invention may be a five-band antenna with three AISG ports shown in FIG. 2, where the five-band antenna with three AISG ports presents three groups of AISG ports and five remote electrical tilt units externally. The remote electrical tilt antenna device provided by the embodiment of the present invention is not limited thereto. The following describes the remote electrical tilt unit in the remote electrical tilt antenna device provided in the embodiment of the present invention.

FIG. 3 is a schematic structural diagram of Embodiment 1 of a remote electrical tilt unit according to the present invention. As shown in FIG. 3, a remote electrical tilt unit 10 provided in this embodiment may include a receiving module 11 and a configuration module 12; the receiving module 11 may be configured to receive, through a group of AISG ports of a remote control unit, permission configuration information sent by a first base station; the configuration module 12 may be configured to configure, according to the permission configuration information received by the receiving module 11, management permission of the first base station on the remote electrical tilt unit, where the management permission includes at least control permission and query permission, and control permission on the remote electrical tilt unit can be allocated to only one base station. This embodiment is not limited thereto.

Optionally, the permission configuration information may include control permission configuration information. Correspondingly, the receiving module 11 may be specifically configured to receive first control permission configuration information sent by the first base station through the group of AISG ports of the remote control unit. The configuration module 12 may be specifically configured to notify the first base station of a control permission conflict if the control permission on the remote electrical tilt unit is allocated to one base station; or, allocate the control permission on the remote electrical tilt unit to the first base station if the control permission on the remote electrical tilt unit is not allocated to any base station.

Optionally, the permission configuration information may include query permission configuration information. Correspondingly, the receiving module 11 may be specifically configured to receive the query permission configuration information sent by the first base station through the group of AISG ports of the remote control unit. The configuration module 12 may be specifically configured to configure the query permission of the first base station on the remote electrical tilt unit according to the query permission configuration information.

It should be noted that, each base station that sets up a physical communication connection with the remote electrical tilt antenna can scan all remote electrical tilt units in the remote electrical tilt antenna, and each remote electrical tilt unit can set up a logical communication connection with each base station. In addition, each remote electrical tilt unit supports multiple types of management permission, where the management permission includes but is not limited to control permission and query permission, and the control permission allows abase station to perform all control and query operation commands on a remote electrical tilt unit. Control permission on each remote electrical tilt unit can be allocated to only one base station. If multiple base stations simultaneously request control permission on a remote electrical tilt unit, the remote electrical tilt unit notifies the base stations of a control permission configuration conflict. The query permission only allows a base station to perform an operation of querying information, and does not allow a base station to perform operations such as calibration or downtilt setting on a remote electrical tilt unit. In addition, query permission on each remote electrical tilt unit can be allocated to multiple base stations.

Further, the permission configuration information may further include control permission change information. Correspondingly, the receiving module 11 may be specifically configured to receive the control permission change information sent by the first base station through the group of AISG ports of the remote control unit. The configuration module 12 may be further configured to: if the control permission on the remote electrical tilt unit is allocated to the first base station, allocate the control permission of the first base station on the remote electrical tilt unit to a second base station according to the control permission change information, and change the control permission of the first base station on the remote electrical tilt unit to the query permission according to the control permission change information.

Further, the permission configuration information may further include control permission release information. Correspondingly, the receiving module 11 may be specifically configured to receive the control permission release information sent by the first base station through the group of AISG ports of the remote control unit. The configuration module 12 may be further configured to: if the control permission on the remote electrical tilt unit is allocated to the first base station, change the control permission of the first base station on the remote electrical tilt unit to the query permission according to the control permission release information.

In an actual application, the permission configuration information may be specifically an interface command or a permission configuration file. When a control permission configuration conflict occurs, a user may perform coordination and control the first base station to send permission configuration information to the first base station, to change the control permission of the first base station on the remote electrical tilt unit to the query permission.

According to the technical solution of this embodiment, a first base station is connected to a group of AISG ports of a remote control unit, where the AISG ports provide a connection with at least one remote electrical tilt unit; if control permission on a first remote electrical tilt unit is allocated to the base station, sends control permission change information to the first remote electrical tilt unit, where the control permission change information is used to allocate the control permission of the base station on the first remote electrical tilt unit to a second base station, and change the control permission of the base station on the remote electrical tilt unit to the query permission. In this way, multiple base stations jointly manage a remote electrical tilt unit in a remote electrical tilt antenna, and a problem that it is difficult to locate and troubleshoot a fault when configuration of the remote electrical tilt unit is incorrect is resolved.

FIG. 10 is a flowchart of Embodiment 6 of a method for managing a remote electrical tilt antenna according to the present invention. As shown in FIG. 10, the permission configuration information includes control permission release information, on the basis of the foregoing embodiment, in the method provided in this embodiment, the foregoing S402 may include:

S601: If control permission on a first remote electrical tilt unit is allocated to the base station, send the control permission release information to the first remote electrical tilt unit, where the control permission release information is used to change the control permission of the base station on the first remote electrical tilt unit to the query permission.

According to the technical solution of this embodiment, a first base station is connected to a group of AISG ports of a remote control unit, where the AISG ports provide a connection with at least one remote electrical tilt unit; if control permission on a first remote electrical tilt unit is allocated to the base station, sends control permission release information to the first remote electrical tilt unit, where the control permission release information is used to change control permission of the base station on the first remote electrical tilt unit to the query permission. In this way, multiple base stations jointly manage a remote electrical tilt unit in a remote electrical tilt antenna, and a problem that it is difficult to locate and troubleshoot a fault when configuration of the remote electrical tilt unit is incorrect is resolved.

In this embodiment, it is assumed that a tri-band built-in remote electrical tilt antenna with two AISG ports includes three remote electrical tilt units, a first base station uses a frequency band corresponding to a first remote electrical tilt unit, a second base station uses frequency bands corresponding to a second remote electrical tilt unit and a third remote electrical tilt unit, the first base station is connected to a first AISG port, and the second base station is connected to a second AISG port.

When permission on a remote electrical tilt unit is configured for the first base station and the second base station, the first base station may use the first AISG port to scan the first remote electrical tilt unit, the second remote electrical tilt unit, and the third remote electrical tilt unit. Because the first base station uses the frequency band corresponding to the first remote electrical tilt unit, the first base station sends permission control configuration information to the first remote electrical tilt unit, to configure permission on the first remote electrical tilt unit to control permission. Similarly, the second base station may use the second AISG port to scan the first remote electrical tilt unit, the second remote electrical tilt unit, and the third remote electrical tilt unit. Because the second base station uses the frequency bands corresponding to the second remote electrical tilt unit and the third remote electrical tilt unit, the second base station may send control permission configuration information to the second remote electrical tilt unit and the third remote electrical tilt unit separately, to configure permission on the second remote electrical tilt unit and the remote electrical tilt unit to control permission. In this way, the first base station and the second base station can normally control desired remote electrical tilt units.

In addition, the first base station may also send query permission configuration information to the second remote electrical tilt unit and the third remote electrical tilt unit through the first AISG port, to configure permission on the second remote electrical tilt unit and the third remote electrical tilt unit to query permission, so that the first base station can query information about the second remote electrical tilt unit and the third remote electrical tilt unit. However, the first base station does not have control permission on the second remote electrical tilt unit and the third remote electrical tilt unit, that is, the first base station cannot perform control operations such as downtilt setting and calibration on the second remote electrical tilt unit and the third remote electrical tilt unit, or affect normal control by the second base station on the second remote electrical tilt unit and the third remote electrical tilt unit. Similarly, the second base station may also use the second AISG port to send query permission configuration information to the first remote electrical tilt unit, to implement query of information about the first remote electrical tilt unit.

Further, if control permission on the second remote electrical tilt unit is allocated to the first base station, control permission on only the third remote electrical tilt unit can be allocated to the second base station.

In a feasible implementation manner, the first base station or the second base station may send permission configuration information that includes control permission change information to the second remote electrical tilt unit, to allocate the control permission on the second remote electrical tilt unit to the second base station and change the control permission of the first base station on the second remote electrical tilt unit to query permission. In this way, the second base station can normally control the second remote electrical tilt unit and the third remote electrical tilt unit.

In another feasible implementation manner, when the second base station desires control permission on the second remote electrical tilt unit or intends to control the second remote electrical tilt unit, the second remote electrical tilt unit sends a permission conflict alarm to the second base station. After receiving the permission conflict alarm, the second base station learns that control permission on the second remote electrical tilt unit is configured for the first base station. Then, a user performs coordination and controls the first base station to send permission configuration information that includes control permission release information to the second remote electrical tilt unit, to release the control permission of the first base station on the second remote electrical tilt unit, and change the control permission of the first base station on the second remote electrical tilt unit to the query permission. After the first base station changes permission of the second remote electrical tilt unit, the second base station sends control permission configuration information to the second remote electrical tilt unit again, to configure permission on the second remote electrical tilt unit to control permission. In this way, the second base station can normally control the second remote electrical tilt unit and the third remote electrical tilt unit.

The technical solution of this embodiment implements joint management by multiple base stations on a remote electrical tilt unit in a remote electrical tilt antenna and resolves a problem that it is difficult to locate and troubleshoot a fault when configuration of the remote electrical tilt unit is incorrect.
